MACHINE FOR WINDING A WIRE OR OTHER PROTECTOR AROUND A FLEXIBLEHOSE-PIPE.

Specification of Letters Patent.

Patented July 2, 1907.

- Application filed April 30,1906. Serial No. 314,590.

To all whom it may concern:

Be it known that 1, JOHN PARRIS, a subject of the King of Great Britainand Ireland, residing at 32 Gloster street, Kensington, in the county ofBourke, State of Victoria, Commonwealth of Australia, have inventedcertain new and useful Improvements in Machines for Winding a Wire orother Protector Around Flexible Hose-Pipes, of which the following is aspecification.

My invention relates to rubber or other flexible hose pipes whichrequire a metallic yet flexible protector wound around their exterior.In the past this metallic protector has been applied in various Ways,some of which were both inconvenient and costly.

The objectof my invention is to provide a machine which will perform theoperation without either injury or disfigurement to the hose, and whichwill also form a tight contact with the said hose and accomplish it withboth despatch and little labor.

Referring to the drawings which form a part of this specification Figure1 is a side sectional elevation of my invention. The feed nut is inplace and the pipe is being drawn into it in an unprotected state anddischarged from it wired or protected. Fig. 2 is a view of a plug. Fig.3 is a front view of the reel carrying plate. Fig. 4 is an elevation, ona larger scale, of a split feed nut. Fig. 5 is a perspective view of asolid feed nut which is removed from the reel carrying plate. One wireonly is being fed to the pipe and the first or entering groove or threadis clearly seen.

Similar letters of reference indicate similar or corresponding partswhere they occur in the several views.

My invention includes a frame A above which are bearings B. In thesebearings rotate a hollow spindle O driven by a variable speed conepulley C or other means. Attached to one overhanging end of the saidhollow spindle is the rotating reel carrying plate D. To this reelcarrying plate are attached reel bearings E. In these bearings are reelspindles F, upon which turn the flanged reels G. The desired tensionupon the flanged reels G may be obtained by the nuts on the reelspindles Fby springs or by other means. Upon one or both of the saidflanged reels is placed the wire or like material to be wound around thepipe. If two wires are to be coiled around the pipe both reels are drawnfrom at once, whereas if only one wire is to be coiled only one is used.Inside the hollow spindle is a stationary overhanging receiving tube H.One end of this is secured to a bracket 1 attached to the frame of themachine. The length of the overhanging portion of the said receivingtube, as'also its shape will depend upon circumstances. Protruding fromthe reel carrying plate are feed nut driving studs K. These drive a feednut hereinafter described. If necessary they may have nuts npon theouter end or the said feed nuts may be retained to the reel carryingplate in any other well known way.

Fitting upon the driving studs K and in the center of the plate is thesplit or solid feed nut L. When split this consists of two halves heldtogether by bolts M. In each half is a hole to accommodate a drivingstud and there is also a separating screw N. These separating screwsenable the two halves to be separated and thereby admit a larger pipeinto the said nut. The mouths of the holes near the joint are enlarged.

Through the center of the said feed nut is a feed hole around which is aspiral feed groove or thread 0. The pitch of this will depend upon thepitch that the wire or other material to be wound upon the pipe is toassume. Instead of there being a square groove as shown it may be roundat the roots and at the points, or be of any other shape. Instead ofthere being one groove, there may be two. The first entering groove inthe hole is marked P (see Fig. 5). The front or leading in end Qprotrudes and has a guideway B. therein. Over the back edge S(hereinafter called the rubbing edge) of the guideway the wire or othermaterial to be wound, rubs in its passage from the reel to the pipe. Thesaid rubbing edge may, if necessary, be provided with a roller or seriesof rollers.

Opposite to the reel carrying plate as seen in Fig. l are two pipeholding wheels T placed edge to edge. These have circular grooves Utherein and the said grooves may be covered with emery cloth or any pipegripping material, or they may be roughened or circumferentiallyrecessed in any well known way to prevent the pipe from turning. Thebearing V supporting the said wheels is so designed that one or both ofthe wheels can be removed or replaced without difficulty. Below thebearings V and preferably integral therewith is a turn table arm W. Thisis attached to the top of a turn pin X. Said turn pin X turns within astandard Y and is locked in the position shown in Fig. 1 by a lockingpin Z. In the end of the pipe Z to be protected I insert a wooden orother plug. This has a shank A and a head B between which head and shankis a step or shoulder O In the head or the plug is a wire holding holeor holes D The cycle of operations with my invention is as follows;Thepipe Z to be protected, has inserted therein the shank A of the plug, sothat the step 0 bears against the pipe end. The operator then places theplug head near the feed nut L and passes into one of the wire holdingholes D, the end of the protecting wire E He then bends the wirepartially around the plug and passes the plug head into thefeed not sothat the protecting wire E enters into the first or entering groove P.He then holds the pipe to prevent it from turning and starts themachine. This turns the hollow spindle O, the reel carrying plate D,

and with it the feed nut L. As the feed nut and the reel carrying platerotate the protecting Wire E is drawn from the reel and into the grooveP. As it is drawn into the grooves O the pipe is moved longitudinally asseen by the direction of the arrow shown in Figv 1. When once the pipehascommenced passing into the hollow spindle C the operator turns thepipe holding Wheels T in the direction shown in Fig. 1. He then elevatesthe top wheel to rest the pipe on the groove in the top of the bottomone.- The locking pin Z is now dropped into position. The pipe continuesmoving toward the stationary overhanging receiving tube H, from theouter end of which it is discharged ready for use.

Having now described my invention, what I claim as new and desire tosecure by LettersPatent is:

1. In a machine for wiring hose, the combination of a rotatable spindle,a reel-carrier connected to one end thereof, a feednut having aninternal wire-guiding-thread and provided with a projecting end having awire entering groove provided with a rubbing edge, and means forconnecting the wire end to the end of the hose.

2. In a machine for wiring hose, the combination of a rotatable spindle,a reel-carrier connected to one end thereof, and a feed-nut providedwith eyes adapted to engage studs on the reel-carrier and cause it torotate therewith, said feed-nut having an internal wire-guidingthretldand provided with a projecting end having a wire entering groove,substantially as described.

3. The herein described machine, comprising a tubular rotatable spindle,a reel-carrier on one end thereof provided with studs, a removablefeed-nut having eyes adapted to engage the studs on the reel-carrier,and a cylindric portion adapted to enter the spindle and also having aninternal wire-guiding'and feeding-thread, and a projecting portionhaving a wire entering groove connecting with the thread.

4. The combination of a tubular rotatable spindle, a receiving tube inone end thereof, a reel-carrier on the opposite end thereof, a removablefeed-nut formed in two sections, and means for adjustably connecting thesections, said nut having a cyiindric portion adapted to enter thespindle and having an internal wire-guidingand feedthread, and a wireentering groove connecting with the thread.

5. The herein described machine, comprising a tubular rotatable spindle,a reel-carrier on one end thereof provided with studs. a removablefeed-nut having eyes adapted to engage the studs on the reel-carrier,and a cylindric portion adapted to enter the spindle and also having aninternal wire-guiding-and feeding-thread, and a projecting portionhaving a wire entering groove connecting with the thread; with means forattaching the end of the wire to a hose to enter same into the feed-nut,and means for supporting the enteringhose adjacent the feed-nut.

In testimony whereof I afiix my signature in the presence of twosubscribing witnesses.
